Characterization of apricot stone shells as a rapid filter medium

What is it about?

Two different size fractions of crushed apricot stone shells were prepared and characterized to investigate the use of this material in granular filters.The leaching tests were performed to quantify the amount of organic matter released from apricot stone medium in water. The Ives’ filterability test was employed to evaluate the effectiveness of removing particulates from a surface water as a function of apricot stone fraction size and coagulant dosage.

Why is it important?

Ives’ Filterability Index test was applied to two fractions of apricot stones. This test may be a useful tool for a preliminary and quick evaluation of variables such as coagulant type, dosage, filter medium size, and filtration rate, although it cannot be expected to replace pilot-scale testing.
